The idea that there will be anything like a fair election in 2028 seems increasingly quaint.

Oh, there will absolutely be something like a fair election in 2028 - though it's very possible that neither party will consider it fair, especially if it's close. We're witnessing first-hand the Founders' wisdom in not letting the federal government be in charge of federal elections. That's always been a source of frustration for good-government types who wanted to reform voting measures and reign in state practices they thought were discriminatory. But now that the rubber is hitting the road, having decentralized state governments run their own federal elections outside the thumb of whoever happens to be President is a rather nice thing to have.

It's pretty unlikely that any of the important states for the 2028 election will radically change their election processes from what they've always been. It's exceedingly likely, though, that almost all of them will change their election processes in small ways over the next three years - which small ways will be regarded by whichever party dislikes them as a monumental retreat from the core concept of fair elections. Which won't be true, but which will lead many deep partisans to conclude that the other side is cheating in a way that undermines the fairness of the elections. Even though the elections will still be as roughly fair as they always have been.
